Schedule Subnets

Subnets are a set of tasks in a project that have dependencies among themselves. During Autoschedule, you can choose to calculate and display separate critical paths for each subnet and for each task that does not have dependencies. Otherwise, only one critical path, the longest path, is calculated for the project. Use the Subnets (All Projects) check box on the Scheduling tab to specify whether you want CPM to calculate the project's critical path separately for each subnet.

You have the following benefits of scheduling subnets:

• If you are working with a master project that contains multiple projects, you can calculate and display the critical path of each subproject and not just the longest critical path.
• If you are working with a project where you have structured the work breakdown structure to support multiple concurrent critical paths, you can display all critical paths.
• If you have a project that contains management tasks that span the project's life, you can display the management tasks and the true critical path.

The following procedure explains how to set up your project to calculate separate critical paths.

Follow these steps:

1. Click Project Properties in the application menu.
2. Open the Scheduling tab.
3. Select the Subnets (All Projects) check box in the Critical Path section.
4. Complete one of the following steps to calculate separate critical paths for your project:
   • Autoschedule your project.
   • Calculate the critical path.
